Figure 2From: Surface roughness effects on the frequency tuning performance of a nanoelectromechanical resonatorResonance properties of frequency, temperature changes from electrothermal voltage, and signal-to-noise ratio of resonant frequency. (a) The resonance properties of the electrothermally tuned frequency at various voltages. (b) The temperature changes resulting from the electrothermal voltage. (c) The signal-to-noise ratio as a function of the resonant frequency.Back to article page
